1. Let M denote set of m&ms in a bag. This consist of red, yellow, green, blue and brown candies.
a. Device on equivalence relation on M.
b. Define relation R on M by: aRb if and only if either: a is green or b is blue, or, a is yellow abd b is not yellow. Is R symmetric, reflexive, transitive or anti-symmetric? Explain.
2. On set Zx(Z not including {0}) define relation R (a,b) a,b e Z, b#0 as follows:(a,b) R (c,d) if and only if ad=bc. Prove that R is an equivalence relation.
